“The story is about Bolt, a white German Shepherd who has lived all his life on the set of a TV show in which he portrays a superhero dog, and as a result thinks that his superpowers are real. Later, he gets accidentally separated from the studio. He then meets a female cat named Mittens and a hamster named Rhino who never leaves his exercise ball, and eventually he discovers that all of his powers are fake.” Wikipedia
